So you are in the good and bad bacteria camp then. How can one believe that some bacteria are good and some are bad when they have already found the supposed bad bacteria in healthy individuals (like strep and TB for instance). We are often told we will die unless we take their 'medicine' that is how they sell it so well. Look at chemo!! They did an experiment on some poor monkeys to see how they faired with NO bacteria. They were bred in a sterile environment and delivered by caesarian section to keep them sterile and guess what. They all died within 10 days. Bacteria are not only in our digestive system, every organ of our body has it's own microbiome too.
